管材的锯削：选用细齿锯条，当管壁锯透后随即将管子沿着推锯方向转动一个适当角度，再继续锯割，依次转动，直至将管子锯断。锯割时管子必须夹正。

Cutting of pipe: select a fine toothed saw blade， when the tube wall is sawed through a proper angle along the direction of the push saw， then continue sawing and turn， until the pipe is sawed. When sawing is cut，fastener种类， the pipe must be clamped.

增设强压功能。即对卸料镶块压料部加厚尺寸(正常的卸料镶块厚H 0.03mm)，以增加对凹模侧材料的压力，从而***冲切时冲压件产生翻料、扭曲变形。凸模刃口端部修出斜面或弧形。这是减缓冲裁力的有效方法。减缓冲裁力，即可减轻对凹模侧材料的拉伸力，从而达到***冲压件产生翻料、扭曲的效果。

日常模具生产中，fastener型号，应注意维护冲切凸、凹模刃口的锋利度。当冲切刃口磨损时，材料所受拉应力将增大，从而冲压件产生翻料、扭曲的趋向加大。

压住材料。克服传统的模具设计结构，在卸料板上开出容料间隙(即模具闭合时，卸料板与凹模贴合，而容纳材料处卸料板与凹模的间隙为材料厚t-0.03～0.05mm)。如此，冲压中卸料板运动平稳，fastener厂家，而材料又可被压紧。关键成形部位，鞍山fastener，卸料板一定做成镶块式结构，以方便解决长时间冲压所导致卸料板压料部位产生的磨(压)损，而无法压紧材料。

Press the material. In order to overcome the traditional mold design structure， the clearance of material is opened on the discharge plate (i.e.， when the die is closed， the discharge plate and the die are fitted， and the gap between the discharge plate and the die is t-0.03 to 0.05mm). In this way， the discharging plate moves ***oothly， and the material can be pressed tightly. In the key forming part， the discharge plate must be made into an inlaid structure to facilitate the solution of the grinding (pressure) loss caused by the pressing part of the unloading plate for a long time， and the material can not be pressed.
